In Fig. REF  (a) we present a plot for the number of droplets as a function of time. The early part is dominated by nucleation. The late time decay is due to growth. In part (b) of this figure we have shown a plot of \(-{dN_d/dt}\)  versus \({N_d}^2\) . There the focus is on the late time growth part. Thus, we have shown data from \(t=5000\)  onward. The linear behavior on a double-log scale indicates a power-law. We expect [1]} an exponent 1 for diffusive coalescence — see Eq. (REF ) and related discussion. That indeed is observed. This also indirectly validates the Stokes-Einstein-Sutherland [2]}, [3]}, [4]} relation in this extended context.
